For R&D scientists and product formulators, a deep understanding of chemical specifications is fundamental to successful application development. R404A refrigerant gas, widely used in medium and low-temperature refrigeration, presents a precise set of technical characteristics that dictate its performance. As a manufacturer committed to transparency, we provide a detailed look at these specifications, empowering our B2B clients with the knowledge they need.

R404A is an HFC blend, recognized for its efficacy as a replacement for R22 and R502. The composition is typically around 44% R-125, 52% R-143a, and 4% R-134a. This specific blend is engineered to achieve desired thermodynamic properties for refrigeration applications. From a purity standpoint, our industrial-grade R404A consistently achieves 99.8%. This high level of purity is crucial, as even trace impurities can negatively affect system performance. For instance, moisture content is kept below 10ppm, and acidity below 0.0001%. These stringent controls prevent corrosion, oil degradation, and the formation of harmful acids within the refrigeration circuit, ensuring system longevity and operational reliability.

The key identifiers for R404A are its CAS numbers: 354-33-6, 420-46-2, and 811-97-2. These numbers provide a unique identification for regulatory and technical referencing. Understanding these identifiers is essential when you need to buy R404A refrigerant gas, especially when placing international orders or complying with import regulations. For formulators, knowing these numbers ensures they are sourcing the correct chemical compound for their research and development projects.

The physical properties of R404A are also critical. It is colorless and non-turbid, with a faint ethereal odor. Its boiling point at 101.3 KPA is -46.60°C. The density at 30°C is 1017.20 Kg/M³. These properties inform how the refrigerant will behave under various operational pressures and temperatures within a refrigeration system. When considering procurement, buyers should also be aware of the Global Warming Potential (GWP) of R404A, which is substantial. While it remains a critical refrigerant for many applications, awareness of its environmental impact is growing, driving research into lower-GWP alternatives.

For R&D scientists and product formulators, sourcing R404A from a reputable manufacturer ensures consistency and adherence to these precise technical specifications. This allows for predictable performance in experimental setups and final product formulations. We encourage you to inquire about our technical documentation and to discuss your specific needs. Understanding these details is the first step towards leveraging R404A effectively and exploring its role in current and future refrigeration technologies.
